After months of urgent entreaties to both the Ukrainian and Russian governments to allow the International Atomic Energy Agency access to the embattled Zaporizhzhia nuclear plant, IAEA director general Rafael Mariano Grossi yesterday set off for the facility, accompanied by a team of nuclear security, safety, and safeguards experts.

The Department of Energy’s National Nuclear Security Administration has redirected about $10 million from the International Atomic Energy Agency’s low-enriched uranium fuel bank to efforts supporting the peaceful uses of nuclear technology and to fight cancer.

LA GRANGE PARK, Illinois – The American Nuclear Society (ANS) sent a letter to California state legislators urging quick passage of bipartisan legislation (Senate Bill 846) to extend operations of Diablo Canyon nuclear power plant.

A bill to extend operations at California’s Diablo Canyon nuclear plant beyond 2025 debuted last evening in the California legislature. Lawmakers have until Wednesday—the end of the current legislative session—to vote on the measure.

Coauthored by State Sen. Bill Dodd (D., Napa) and Assemblymember Jordan Cunningham (R., San Luis Obispo), Senate Bill 846 includes a $1.4 billion forgivable loan to Pacific Gas and Electric (PG&E), the plant’s owner and operator, matching the amount in the August 12 proposal from Calif. Gov. Gavin Newsom. Instead of Newsom’s proposed option for a 10-year life extension for the facility, however, SB 846 would keep the plant running for an additional five years only.

Representatives of Ultra Safe Nuclear Corporation (USNC) of Seattle, Wash., and Hyundai Engineering of Seoul, South Korea, traveled last week between USNC project sites in Oak Ridge, Tenn., and Ontario, Canada, to sign two agreements extending their collaboration on the deployment of USNC’s high-temperature, gas-cooled Micro Modular Reactor (MMR). The agreements expand on a business cooperation agreement signed in January 2022 and an engineering agreement signed in June, and follow the closure earlier this month of a previously announced $30 million equity investment after its review by the U.S. Treasury Department’s Committee on Foreign Investment in the United States.

The American Society of Mechanical Engineers/American Nuclear Society Joint Committee on Nuclear Risk Management (JCNRM) has issued a new edition of its flagship standard, ANSI/ASME/ANS RA-­S-­1.1-­2022, Standard for Level 1/Large Early Release Frequency Probabilistic Risk Assessment for Nuclear Power Plant Applications. This standard was approved by the JCNRM, the ANS Standards Board, and the ASME Board on Nuclear Codes and Standards before being approved on May 11 by the American National Standards Institute (ANSI), earning the title of an American National Standard. With most of the text stable for the past year, the production process was started early, allowing the 400-­page standard to be published on May 31, 2022.

The United Kingdom’s Rolls-Royce SMR has signed an exclusive agreement with ULC-Energy—a Dutch nuclear development company established in 2021—to deploy small modular reactor stations in the Netherlands. (ULC stands for Ultra Low Carbon.)

Across the country, supply chain issues continue making the news: price escalation, inflation, logistical delays, scarcity of products and services, obsolescence, risk associated with just-­in-­time inventory, equipment and service quality, and—especially in nuclear—the financial pressures to reduce costs while maintaining our focus on safe, secure, and reliable plant operations.

Unfortunately, these are not new challenges for nuclear supply chain professionals.

In fact, in 2001, the Nuclear Energy Institute formed the Nuclear Supply Chain Strategic Leaders Group (NSCSL) in conjunction with the Institute of Nuclear Power Operations (INPO) and Electric Power Research Institute (EPRI) after an American Nuclear Society Utility Working Conference networking event. The NSCSL is composed of utility supply chain managers and directors and serves as the “community of practice” for these subject matter experts. I am privileged to be an NSCSL participant and an Entergy team member. The NSCSL was designed to be the industry go-­to group for materials and service collaborations and needed supply chain solutions.

NuScale Power yesterday announced the signing of a memorandum of understanding with Estonia’s Fermi Energia, a company focused on small modular reactor development to address the Baltic state’s climate and energy security goals.

Under the MOU, Fermi Energia will evaluate the Portland, Ore. – based firm’s small modular reactor design for deployment in Estonia. (There are no nuclear power facilities in Estonia or in the other Baltic countries, Latvia and Lithuania.)

Washington state’s Department of Ecology and the U.S. Department of Energy have agreed on a plan for how to respond to two underground tanks that are leaking radioactive waste, as well as any future tank leaks, at the Hanford Site near Richland, Wash.

In April 2021, following a year-long leak assessment, the DOE announced that Hanford’s Tank B-109 is leaking waste into the surrounding soil. Tank T-111 was discovered to be leaking in 2013. Currently, Tank B-109 is leaking about 1.5 gallons of waste per day, and Tank T-111 is leaking less than a gallon a day, according to the DOE.

Energoatom, Ukraine’s nuclear plant operator, is reporting that Units 5 and 6 at the Zaporizhzhia plant—currently the facility’s only operational reactors—were disconnected from the country’s power grid early in the morning of August 25.

The Zaporizhzhia site has been under the control of the Russian military since March 4, just days after Russia commenced its invasion of Ukraine.

China’s Taishan-1, which was shut down last summer due to damaged fuel rods, resumed operations on August 15.

The plant briefly made headlines last summer—as much for the damage inside the reactor as for the media fallout. In June 2020, plant operators found damage to the cladding on about five of the 60,000 fuel rods in Taishan-1, one of the plant’s two 1,660-MW EPRs. What happened next seemed like a bad game of “telephone.”

The Solid Waste Management Facility (SWMF) at the Department of Energy’s Savannah River Site recently was subject to an enhancement program designed to improve procedure format and quality. The program has led to a greater efficiency and a streamlined procedure review process at the facility, according to the DOE’s managing and operating contractor at SRS.

Kishida

Having already declared last month his government’s intention to return to service as many as nine idled power reactors in order to ensure stable supplies of energy this winter, Japanese prime minister Fumio Kishida yesterday called for additional restarts and endorsed the development and construction of next-generation nuclear plants, according to reports from various news outlets, including Nikkei Asia, the Washington Examiner, and the Los Angeles Times.

Kishida made the comments at the second meeting of Japan’s GX (Green Transformation) Implementation Council, a new group tasked with helping the country achieve carbon neutrality by 2050.

Rod Adams

In 1993, after a decade in the nuclear navy during which time I fell in love with nuclear power, I left the service and founded Adams Atomic Engines (AAE) to develop a small, portable engine powered by fission. Today, AAE would be seen as a venture developing an SMR, but back then, I couldn’t find enough investors who understood or believed in my vision.

That was deeply disappointing, but over the next several decades I stayed connected with other innovators who had similar visions. I found great satisfaction interviewing members of the industry through the Atomic Show podcast and publishing news about advanced nuclear developments on my website, Atomic Insights.

Fast forward, and the world is in a very different place. A few years ago, I was contacted by an investor who saw the potential of advanced nuclear designs to meet the world’s needs for a clean energy revolution, and I was thrilled. Even in 2019, there were almost no venture capitalists focusing on what was happening in the nuclear industry—probably because nuclear had never fit the venture capital model, which involves investing in the equity of a growing private venture.

X-energy has been having a good year. Not only did Dow announce plans to invest in the company’s high-temperature gas reactor (HTGR) technology and deploy an Xe-100 reactor at a U.S. Gulf Coast facility for power and process heat by 2030, in parallel with the Xe-100 demo planned for Washington state with support from the Advanced Reactor Demonstration Program (ARDP), but X-energy’s fuel subsidiary, TRISO-X, has applied for a fuel facility license and aims to have a commercial fuel plant operating in 2025, and Canadian provinces are signaling their interest in the technology. And while news of Dow’s investment broke with well-deserved fanfare, the company’s serious interest in HTGRs—and federal support for HTGR development—goes way back.

Mine rescue teams from the Department of Energy’s Waste Isolation Pilot Plant (WIPP) finished in the top 15 in competitions at the first-ever joint Coal, Metal, and Nonmetal National Mine Rescue Contest in Lexington, Ky., held on August 7–12.

Akkuyu Nuclear, the Ankara-based Rosatom subsidiary established to manage Turkey’s Akkuyu nuclear plant project, has announced the successful mounting of the Unit 1 polar crane. The operation was carried out using a Liebherr LR 13000 crane and took approximately four hours, according to Akkuyu Nuclear.

Also referred to as a circular bridge crane, the polar crane operates on a circular runway located near the spring line of the containment building. It is used for a wide range of loading and lifting tasks within containment, including reactor-head removal/replacement and fuel loading/unloading.

The American Nuclear Society is offering the hour-long members-only webinar “Inflation Reduction Act: What's in it for nuclear?” on Friday, August 26, starting at 1:00 p.m. EDT.
